2-Ethylpyridine can be used to prepare Dimethindene Maleate. It is also used to study its effect on the proliferation and survival of human umbilical vein endothelial cells (HUVECs), HMVECs from lung, and NIH 3T3 cells.
2-Ethylpyridine linked with silica is a popular stationary phase for chiral and achiral separations in supercritical fluid chromatography.
